Re: [Active4d-dev] Web Client Processes and Active4D

[Michael Bond]

Hi, I can't help you  with anything specific but have you tried logging 
the exact page and query string that was passed to A4D at the time. We 
have a generic logging procedure and we have something like:

On Request Start:
$t_requeststring:=requested url+"?"+get query params
// We have all parameters placed into the query parameter collection
log($t_requeststring;string(current process))
// The second parameter is the name of the file to log to
On Request End:
log("Request End";string(current process))
With the matching pair you should be able to see what was being 
processed at the time of the crash, and exactly what was passed to A4D 
on a per process basis. Using a browser or a CLI tool you will be able 
to exactly rerun the call at the time of the crash, minus any session or 
global variables of course. We had freezes a while ago with a4d in the 
past and we found out, using this method, that it was due to rediculous 
user search parameters. ( The client was not dead but just very very 
active and wouldn't process web requests very quickly.)

All the best
